GLASS COMPA Y, a 'oonronarron F PENNSY'LVANI'A 1 j FLUID-Coons]: ROLL" Application meamecember 19,1927. Serial No'; 241,040.

The invention relates to fluidfcooled rolls for usein glass rolling apparatus, such as that shown in the patent- .to FrederickGels tharp No. 1,560,079 of November 3; 1925, or

the patent to Lee, Showers No. 1,579,666 of April 6, v1926, although not'limited to use in the particular apparatus of said patents.

The invention has for its principal objects;

the provision of a roll in which the tendency to warp under the severe heat conditions en'- countered, is reduced to a minimum; theprovision'of a roll, which is uniformly cooled by the fluid employed for that purposeyand the provision of a roll wherein the glass en-i gaging portion may' bereadily renewed,"-

either in part orin whole at a cost whichis roll.

'very small, as compared with. the costof the One embodimentof the invention is illustrated in the accompanying-drawings, wherein:

Figure 1 is a longitudinal section through the roll. Fig. 2 illustrates the application of the roll in an apparatus such as that shown in the Showers .patent referred to. Fig. 3 is l a partial end elevation and partial section 2 on the line TIL-III of Fig. 1. Fig 4 is a' partial end elevation and-partial section on.

rolled into a sheet which passes along the roller bed 7 into the leer where it is annealed.

One of the difficulties encountered in arolling operation of this kind is that of.main-, taining the roll 3 at a proper temperature. It must be adequately cooled and this cooling should be uniform from one end of the roll to the other in order to avoidwarping of the roll, as such Warping introduces strains resulting in a rapid'deterioration of theroll ENNsYLvAN'IA, AssI GNoR-iro rir'rsntinen PLATE I and furtheriproduces asheetwhich is not of uniform thickness. The present inventionii's designed to provide acoolingarrangement .WhlCllWlll give the necfessar'y uniformity' 'n cooling and in which 'anylw'ar'ping is reduced I to aminimumf V r The roll 3. comprises the casing 8, prefer ably of cast iron, having the central portion cored out or counterbored t j the chamber 9. Bearing portions 10,110 arepro vided'at the ends of theroll fQI" S lPP Qrting it in 'suitable jou'rnals." One. end isprovfidged;

The swivel :13 isprovided with passages which register-with the passages 17 17 a leadingto the centr of the roll, ,while the swivel .14 is provided with a passage registering; with 'the' passage 18',

which latter communicates with the interior of the casing. At its other endrtheroll is provided with a capinembe'rQlS held in place bythe bolts 20 and carrying-"the three swivels 21, 22and 23, the outerfswi-vel'being held'in position by the'member 24Jwhich-is secured to the cap 19 by the bolts 25.;Th .SWivelsj21and 22 areprovided Witli'zinlet' passages 26 and 27, whose inner ends :registerfwith[the-passages28 and 29, leading .to the centrallportion of the casing whiletheswivel 23' is provided with an outlet 30 registeringwith' the'p as sage .31 leading to theinterior of the'ca'sing';

f Mounted upon .the. casing is series of sleeves or collars 32, also preferably of cast iron or steel. v.lThese Icollars' or sleevesare shrunk on'tothe casing8 andare positioned with their ends closely adjacent, butlont of actual contact. Additionalisecuring means are provided forthe end collars or sleeves in the ioim'of the nuts; Bitand 34,- which; are threadedupon the ca'singl' The V rolling jsurfaceinade up of the collars 82 is notrsubject ,to warping to the same extent as-a one-"piece .sleeveior casing, asthe individual collars due to the r separation can expand andcontract longitudinally. of the: to "a certain "L l-d extent without affecting the other members of the series. This arrangement has the further advantage thatthe series of collars may be removed and replaced when worn to such an extent that they are no longer serviceable, leaving the main :portionof the roll intact forfurther service. v

''Water is circulated into the roll by means 0H two et flefr re 3 and 3.6 3 13 d 38, such sets of pipes being in c ce tne relation, as shown in 1 and having the closures 38 and 39, and 41 at their inner ends, the closures 38 and 39 being provided with central outlet passages42-a'nd 43. These. supply pipes are screw threaded into the members lland 19 at; their innergends, and are supported intermediate their ends by means of the studs 144 which are threadedat their inner ends into the walls of the pipes 37 'and38 and engage the inner wallsof the casing at. their outer ends. The spacing collars also serve to support the inner pipes from the outer ones. The i'nner fpip'es 35 and 36 are supplied withfcoolingijfiuid, such water from the p'assages28'and 17 respectively, whilelthe o ter pipes 37 and, 38' are supplied with waterfrom the passages 29 and 170. The water; fsup'pliedv to the pipes'35 and 36 flows as; theoute'r end thereof and is distributed through the perforations 46, some ofit also passingthrou'gh'the openings'42 and 43.
